3A LOW DROPOUT LINEAR REGULATOR
General Description
Features
Data Sheet
AZ1085C
The AZ1085C is a series of low dropout positive volt-
age regulators with a maximum dropout of 1.5V at 3A
of load current.
The series features on-chip thermal shutdown. It also
includes a bandgap reference and a current limiting cir-
cuit.
The AZ1085C is available in 1.5V, 1.8V, 2.5V, 3.3V,
5.0V and adjustable versions. The fixed versions inte-
grate the adjust resistors. The adjustable version can
set the output voltage with two external resistors.
The AZ1085C series is available in standard packages
of TO-263-3, TO-263-2, TO-252-2 (3) and TO-252-2
(4).
· Low Dropout Voltage: Typical 1.3V at 3A
· Current Limiting and Thermal Protection
· Output Current: 3A
· Current Limit: 4.5A
· Operating Junction Temperature: 0 to 125oC
· Compatible with Low ESR Ceramic Capacitor
· Line Regulation: 0.015% (Typ)
